DOOR-FASTENER.

Specification of Letters Patent.

Patented Apr. 26, 1921.

Application filed January 27, 1920. Serial No. 354,382.

To all whom it may concern Be it known that I, LAWRENCE L. SWAN, a citizen of the United States, residing at East Liverpool, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Door- Fasteners; and I do hereby declare the following to be a full, clear, and exact descrip-' tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved door fastener which will be connected with a door for securely but releasably holding the door in a closed position and one object of the invention is to provide a fastener having an improved means for slidably mounting locking bars and for rota-tably mounting means for moving the bars inwardly or outwardly.

Another object of the invention is to so construct this lock that the locking bars may have their inner end portions slidably mounted in a block or casting and provided with rack teeth engaged by a pinion rigidly mounted upon a shaft rotatably mounted in the block or casting and provided with a turning handle.

Another object of the invention is to so construct this look that it may be easily and quickly moved to a locked position and retained in the locked position.

Another object of the invention is to so construct this look that it will comprise a comparatively few number of parts which will be strong and durable and not liable to get out of order.

This invention is illustrated in the accom panying drawing, wherein:

Figure 1 is a view showing a door in elevation and having the improved lock associated therewith;

Fig. 2 is an enlarged view showing the lock in elevation and looking at the outer face thereof Fig. 3 is a view similar to Fig. 2 looking at the inner face of the lock;

Fig. 1 is a top plan view of the lock.

Fig. 5 is a fragmentary view in elevation showing the lock provided with a modified form of the turning handle.

Fig. 6 is a vertical sectional view taken along the line 66 of Fig. 5.

' This lock is used in connection with a door 10 which will be movably associated with the frame 11 for opening and closing.

The lock is carried by the door and the sockets 12 into which the locking bars 13 will be mounted upon the frame 11 upon opposite sides thereof. The locking bars 13 are slidably connected with the door by guide brackets 14 and have their inner end portions extending into transversely extendmg grooves 15 formed in the disk or block 16. This block 16 is secured to the door by screws or other fasteners 17 and has its inner face portion cut away between the groove 15 to provide a central pocket 18 111 which is positioned a pinion 19, the teeth of which engage the teeth of the racks 20 formed along the inner end portions of the bars 13. This pinion 19 is rigidly mounted upon a shaft 21 which is rotatably carried by the block 16 and extends through the neck 22 beyond the outer end of the neck. A handle 23 is provided with a head 24 firmly fastened upon the extended outer end portion of the shaft 21 and it will thus be seen that when the handle is moved to rotate the shaft, the pinion will be rotated and the locking bars moved inwardly or outwardly according to the direction in which the handle is moved. It will thus be seen that when the door is closed the locking bars may be moved downwardly into the sockets 12 and the door securely locked until the handle is again turned to withdraw the locking bars. If it is desired to provide additional securing means for the door the handle 23 may have its free end portion provided with a head 25 having an opening 26 formed therein thus permitting a pad-lock 27 to be passed through the openings of the head 25 and through a similar opening formed in the arm 28 of a cleat 29. This cleat will be secured to the door and it will be readily seen that when the lock is put in place it will be impossible to move the handle and draw the locking bars inwardly. If desired a cross strip 30 may be secured to the inner face of the disk 16 to hold the inner end portions of the locking bars in the grooves or seats 15. The cleat 29 lies in the path of the handle and consequently normally limits the movement of the latter to prevent complete disengagement of the locking bolts from their operating means, however, the cleat may be conveniently removed from the door to allow movement of the handle suflicient to disengage the teeth of the locking bolts from the pinion 19 and allow the locking bolts to be moved out of the grooves 15. It will be apparent that the bolts 13 may be completely removed from the plate 16 and the door simply by sliding movement. It is advisable to remove the bolts at times to lubricate and clean the teeth, especially When the device is used on heavy doors.

WVhat is claimed is 1. A lock including a plate for attachment to the object to be looked, a bolt, means to support the bolt for free sliding movement to locked and unlocked positions and complete removal from the plate, means on the plate operable to slide the bolt, and abutment means engageable by said last means to normally prevent movement of the second means out of operative relation with the bolt.

2. A lock including a plate for attachment to the object to be locked, bolts, means on the plate to support the bolts for free sliding movement to locked and unlocked positions and complete removal from the plate, said bolts having gear teeth, a pinion meshing with said teeth, a handle to operate said pinion, and an abutment for the handle to normally prevent suflioient movement of the handle to disengage the pinion and teeth.

In testimony whereof I aflix my signature in presence 01" two Witnesses.
